10 void explain_utimensat_or_die(int fildes, const char *pathname, const

13 struct timespec *data, int flags);

16 The explain_utimensat_or_die function is used to call the utimensat(2)
17 system call. On failure an explanation will be printed to stderr,
18 obtained from the explain_utimensat(3) function, and then the process
19 terminates by calling exit(EXIT_FAILURE).
20
21 The explain_utimensat_on_error function is used to call the utimen‐
22 sat(2) system call. On failure an explanation will be printed to
23 stderr, obtained from the explain_utimensat(3) function, but still
24 returns to the caller.
25
26 fildes The fildes, exactly as to be passed to the utimensat(2) system
27 call.
28
29 pathname
30 The pathname, exactly as to be passed to the utimensat(2) sys‐
31 tem call.
32
33 data The data, exactly as to be passed to the utimensat(2) system
34 call.
35
36 flags The flags, exactly as to be passed to the utimensat(2) system
37 call.
38
40 The explain_utimensat_or_die function only returns on success, see uti‐
41 mensat(2) for more information. On failure, prints an explanation and
42 exits, it does not return.
43
44 The explain_utimensat_on_error function always returns the value return
45 by the wrapped utimensat(2) system call.
46
48 The explain_utimensat_or_die function is intended to be used in a fash‐
49 ion similar to the following example:
50 explain_utimensat_or_die(fildes, pathname, data, flags);
51
53 utimensat(2)
54 change file timestamps with nanosecond precision
55
56 explain_utimensat(3)
57 explain utimensat(2) errors
58
59 exit(2) terminate the calling process
